multi dimensional optim problem
I am attempting to use optim to solve a neural network problem. I would like to optimize coefficients that are currently stored in a matrix
Y=270 x 1
X= 27- x 14
b1= 10x14
b2= 11x1
V= 10 x 14 set of prior variances.
I have the following function:
posterior.mode1=function(y,X,b_0,b2,V) {
log.like=function(b1) {
a_g=compute(b1)
z_g=tanh(a_g);
z_g=cbind(1,z_g)
p=softmax(z_g%*%b2);
a=sum(y*log(p)+(1-y)*log(1-p));
return(a);
}
compute=function(b1)...

R Newbie: quantmod and zoo: Warning in rbind.zoo(...) : column names differ
Hello;
I am trying following but getting a warning message : Warning in
rbind.zoo(...) : column names differ, no matter whatever I do.
Also I do not want to specify column names manually, since I am just
writing a wrapper function around getSymbols to get chunks of data
from various sources - oanda, dividends etc.
I tried giving col.names = T/F, header = T/F and skip = 1 but no help.
I think
